Install sircbot

Configue sircbot

Create sircbot scripts folders and files

Sircbot will use an folder for the channel where is logged in. Lets say we will use it at the "test" channel.
The folder path is: /etc/sircbot.d/#channel

Example

Lets see an example:

Our bot will be named kumquat and we will join at the #test channel in the irc.ddd.ddd server.

vi /etc/conf.d/sircbot

Change name, server and channel

sircbot_opts="-n kumquat -s irc.ddd.ddd"
sircbot_channels="#test"

Create folder bot.

mkdir /etc/sircbot.d/#test -p

Create the lua scrip file for our bot.

vi /etc/sircbot.d/#test/commands

#!/usr/bin/lua
-- Scripts for kumquat in Lua
args={...}
sender=args[1] -- is the nickname of running the command on IRC
message=args[2] -- is the message or command typed
channel=args[3] -- is the channel name
os.execute("sleep " .. tonumber(1))
-- This command will show: What can i do for you "nickname"?
local kumquatresult = string.find(message, "kumquat")
if kumquatresult ~= nil then
command="echo 'What can i do for you '"..sender.."'?' | sircbot-send '"..channel.."'"
io.popen(command)
end
-- This command will show: Hello there, amigo "nickname"
local kumquatresult = string.find(message, "hi")
if kumquatresult ~= nil then
command="echo 'Hello there, amigo '"..sender.." | sircbot-send '"..channel.."'"
io.popen(command)
end
-- This command will show the current UTC date and time
local kumquatresult = string.find(message, "date")
if kumquatresult ~= nil then
command="date -u | sircbot-send '"..channel.."'"
io.popen(command)
end
-- This command will do a search for a alpine linux package
local kumquatresult = string.find(message, "apk search:[^%d]")
if kumquatresult ~= nil then
local strng = (string.sub(message, 12))
command="apk search"..strng.." | sircbot-send '"..channel.."'"
io.popen(command)
end
-- This command will resolve a host name and ip
local kumquatresult = string.find(message, "host:[^%d]")
if kumquatresult ~= nil then
local strng = (string.sub(message, 6))
command="host "..strng.." | sircbot-send '"..channel.."'"
io.popen(command)
end
-- This command will do a 3 times ping to a server or ip address
local kumquatresult = string.find(message, "ping:[^%d]")
if kumquatresult ~= nil then
local strng = (string.sub(message, 6))
command="ping -c 3 "..strng.." | sircbot-send '"..channel.."'"
io.popen(command)
end

Make the script to be executable

chmod +x /etc/sircbot.d/#test/commands

Giving life to the bot

Starting bot service and adding to boot.

/etc/init.d/sircbot start && rc-update add sircbot default

Troubleshooting

If your bot is not responding as expected, an easy way to troubleshoot is to manually execute the script in /etc/sircbot.d/<#channelname>/<scriptname> with the three agruments.

If your bot responds as expected, then you know that your script works. The problem is that sircbot is not executing the script. Here are two likely causes:

Sircbot is case-sensitive when looking for the channel directory for a script to execute. For example, if you have a channel named "#Alpine", sircbot will look for /etc/sircbot.d/#Alpine/*. If that pathway isn't exactly right, then sircbot will skip that folder. In our example, if you have /etc/sircbot.d/#alpine/script, sircbot will not execute anything in that folder. To fix, simply rename the folder to /etc/sircbot.d/#Alpine/

Sircbot doesn't execute scripts that have a '.' in the name. For example a script named 'listen.lua' will not be executed. Simply rename the script to 'listen'.
